Figure 4:
Electrode Configuration of Single and Multiple Backplane LCDs
Unfortunately, when an LCD has multiple backplanes, it is impossible to control the
segments using static voltages. For example, consider the multiple backplane LCD in
Figure 4. Let’s assume that one wishes to activate the segments in column 1 row 1 and
column 1 row 2. To do this, static voltages can be applied to the C1, R1, and R2 pins.
Suppose in addition to these two segments, one wishes to activate the segment in column
2 row 1. The only way to do this is to apply a static voltage to pin C2, but this will also
cause the segment in column 2 row 2 to become active. So to control any combination of
segments the row and column signals must be time multiplexed (there are other reasons
why static voltages cannot be used on LCDs).
The LCD controller of the C505L has the ability to control 4 backplanes and up to 32
columns. This means that 128 segments can be controlled.

Control of LCDs
Unfortunately, if a voltage difference between two electrodes is maintained for too long,
the liquid crystal may become permanently aligned in one direction, thus ruining the
display. To ensure that the liquid does not become permanently aligned, the voltage
difference between the two plates must be toggled between positive and negative. Since
